3 Claims. (Ci. 189--75) This invention relates generally to a window frame mounting and in particular relates -to improvements in the mounting of metal window frames in connection with pre-fabrcated metal wall sections or panels as used in the Construction of metal buildings.

In mounting a metal window frame or sash in a Window opening formed and bounded by metal wall panels, it is requisite that an air tight seal be formed between the window frame and panels whereby to prevent leakage of air or water therebetween, as well as unnecessary heat transfer to and from the interior of the building. It is thus my principal object to provide a novel manner of scaling the space between the metal window frames and metal panels, and to secure the window frames to said panels after placement of the window frames and sealing material without disturbing the latter.

A further object of the invention is to produce a simple and inexpensive window frame mounting and yet one which will be exceedingly e'ective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a sectional plan of a metal window frame mounted and sealed in connection with metal wall panels in accordance with my invention.

Figure 2 is a fragmentary elevation of the prefabricated metal wall panel used in connection with the present embodiment of the invention;

Referring now more particularly to the characters 'of reference on the drawing, the window opening, to receive the metal window frame, is formed by pre-iabricated metal panels which are constructed in accordance with the disclosure in my copending application for United States Letters Paten-t, Serial No. 183,&19, filed January 7, 1938. such panels each comprise generally a pair of spaced metal plates l Secured in fixed relation by straps 2 connected by spot welding betweer the inturned flanges 3 formed along both the sides and ends of the plates; the panels being entirely filled with heat insulating material 4.

When initially mounted in place. to form a window opening, the adjacent sides or ends of the panels are substantially open to the insulation material 4 (as shown in Fig. 2) and thereafter jamb plates 5, which completely cover such open portions, are arc welded at intervals along the edges to the panel anges 3, as shown at 6. This type of welding is hereinafter called "tack" welding. The plates 5 are of general convex configuration exteriorally, as shown, and adjacent their outer edges are turned in somewhat abruptly, as at 'I for engagement and tack welded connection with the adjacent panel fianges 3 some distance inwardly of the plane of the exterior face of the wall panels surrounding the window opening. The window opening as so constructed is ready to receive the metal window frame therein in the manner hereinafter described.

The metal window frame or sash is preferably of the metal casement type as shown in the present instance and includes outer wall engaging fla'nges 8 and inwardly projecting flanges 9 disposed at right angles to fianges 8 and some distance from the outer edges thereof; there being relatively short fianges H) extending from the inner edge portion of flanges 9 and in a plane substantially parallel to the plane of flanges 8. This is standard metal sash Construction. The casement, of course, supports a window W mounted as usual. The metal casement is mounted in the window opening with flanges 8 engaging the outer plates I of the panels surrounding the opening, and with flanges 9 extending into the opening and spaced from the adjacent flanges 3 of the panels; the flanges li! engaging against plates 5 inwardly of inturned portions 'I in wedging relatio-n. The endless space or cavity C defined by flanges 8, 9 and n, inturned portions 'I of plates 5, and. the adjacent fianges 3 is entirely filled with putty or plastic sealing material of that type known as "mastic" and as indicated at P. Thereafter fianges 8 are tack wel-ded at intervals, as at Il, to the faces of the plates l. This Welding prevents displacement of the metal frame from the window opening and the plastic material forms an air and water tigh t seal between the metal window frame and the wall panels as is desirable.

From the foregoing description it will be readily seen that I have produced such a window frame mounting as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred Construction of the window frame moun-ting, still in practice such deviations from such detail may be resorted to as do no t form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

l. In the combination of a wall having a window opening therein, and a Window frame for said opening, the frame including a fiange surrounding the opening and Secured to the wall, and another fiange disposed in the opening laterally inward from and connected to the surrounding fiange and in spaced relation -to the Wall surface which outlines said opening; and. a jamb plate unit Secured on the wall within said opening, the unit including jamb plates having a general con- Vex configuration exteriorally, said other flange convex configuraton exteriorally and turned in. abruptly at their edge portions adjacent the window frame, said other flange engagng said plates inwardly of the. inturned portions and in wedging relation.

3. In the combination of a wall having a window opening therein, and a window frame for said opening, the frame includinga flange surrounding the 'opening and seen-red to the walL 'and another flange disposed in the opening laterally ini ward from and connected to the surrounding fiange and in spaced relation to the wall surface which, outlnes said opening; a jamb plate unit Secured. on the wall within said opening, the unit includingjamb plates having a general convex configuration exterorally, said other fiange engaging said plates in wedging relation, there being .an endlesscavity thus defined by said flanges and wall surface, and sealing material entirely filling said cavity.
